Owens Lake Dust Mitigation Project – Phase 7, Los Angeles Department of Water and Power (LADWP), Los Angeles, California
City of Los Angeles Department of Water and Power

Preliminary Engineering, Review As-Built Drawings, Site Investigation, Coordination Meetings, Civil and Mechanical Designs, Preliminary & Final Design, Overall Site Plan, Work Area Limit Plan, Grading Plan, Lateral Piping Plan

As a subcontractor, DRC supported design and engineering on the Owens Lake Dust Mitigation Project, Phase 7, for the City of Los Angeles, Department of Water and Power, providing preliminary and final designs.

Our team performed all civil engineering: reviewed as-built drawings for previous Owens Lake improvements; provided specific area civil and mechanical designs; and AutoCAD drafting to prepare preliminary designs for Phase 7 Dust Control Areas and other locations. Preliminary designs included all design criteria. DRC designed and engineered demolition plans of existing improvements: site, work limit, grading, culvert, controlled outlet, spillway, and piping.

For each of the site’s shallow flood areas, DRC developed drawings for an Overall Site Plan, a Work Area Limit Plan, a Grading Plan, and a Lateral Piping Plan. Our team developed Final Design drawings for the shallow flood areas to an overall design level of 100% completion and a final Overall Site Plan for all of the shallow flood areas showing key features such as acres of each area, locations of berks, if any, maximum control elevation of water, inlets and outlets, spillway elevations, turnout locations, laterals, and locations and type of storm drainage control.
Perris Basin Desalination Design Project, Perris Desalter II Test Wells, Eastern Municipal Water District (EMWD) Property or Easement, City of Perris, Riverside County, California
U.S. Army Corps of Engineers Los Angeles District

Project Management, Geotechnical Engineering, Hydrology, Hydrogeology, Geology, Scheduling

DRC’s modified the original services for installing four new test wells for the Eastern Municipal Water District’s (EMWD) Perris Basin Desalination Program in the City of Perris, Riverside County, California. The project required an analysis of formation samples, sieve analyses of drill cuttings, and an analysis of the downhole geophysical logs after drilling commenced. The analysis determined the depth of the well to be 390 feet.

DRC conducted field investigations and developed and installed two new test wells. This included drilling; preparing downhole geophysical and caliper logs; and well construction, development, testing, alignment surveys, color video, disinfection, and a pump foundation. The method for drilling and completing the new test wells at all water-bearing zones produced acceptable properties and water quality identified by EMWD.

The work included reaming, installing blank and louvered well castings, installing gravel pack, and well development. DRC monitored the project, created the work plan, and a project schedule. DRC completed the welding of the steel plate over the top of the well casing, the tubing, and the annular space between the well casing and conductor casing to protect the wells from vandalism.

The final well designs and decision to complete each test well were contingent upon an examination of the formation samples, sieve analyses of drill cuttings, and downhole geophysical logs that were collected and completed during drilling of the pilot borehole. The operational capacity of the new test wells is 300 to 1,000 gallons per minute.
Coordination of the Environmental and Feasibility Portions of the Sports Arena and Ball Fields Project between the City of Pico Rivera and USACE, California
City of Pico Rivera Department of Public Works

$6 Million

Gather Information, Coordination and Meetings, Project Management, Hydrology and Hydraulic Evaluation, Review Geotechnical and Soil Information, Project Report

DRC performed a feasibility review and study for a multi-use building on property adjacent to the San Gabriel River within the Whittier Narrows Recreation area. The City of Pico Rivera maintains a long-term lease on the property, which the U.S. Army Corps of Engineers owns. DRC knows the Corps’ requirements to determine a project’s environmental conditions and its feasibility for development and, as such, provided excellent support to the city for a sports arena and for the area’s long-term development.

DRC staff had direct involvement in the flood evaluation, preparing guidelines and securing approvals for development within the Whittier Narrows area. The environmental portion of the project included a review of certain project details to develop an initial study and an environmental assessment that led to a mitigated negative declaration.

This project contract had two phases:

First phase:

  • Research documentation and review the site;
  • Evaluate flood and water runoff;
  • Review geotechnical and soils information; and
  • Prepare a Phase I report.

Second phase:

  • Coordinate with U.S. Army Corps of Engineers;
  • Develop and send a report to the departments of Fish & Game and Fish & Wildlife for review and comment;
  • Prepare the final report; and
  • Coordinate and oversee work on the project for the city and the Corps of Engineers.
